To a. mhmnfiif um voumermr Bo it known that LWLLLIAM II. llms'rmt, a oitizon of the United States, and a residont oi in thecounty of New York and Stato of New York, have. invented a certain now and useful Improvemont in 'lhormollloottrio Couples, of which the following is a relates to thormo-olooLrio oouplos, and has or its parlviouhu ohjoot to oonstrnot, a oonploin suoh a nmnnor i mt it may he readib' and quickly installed and that the notivo porlion'may be ronon'od or romoved without disturbing the remainder of the con do and apparatus.

For tllis sontially, o' ooniprising a M y invention a sectional or sepornhlo oonplo primary section ary seotion and means adaptod toiirmly mmtho ootor or (old onds living tho oouple and tho point to wlnoh tho loads port ion of tho oon plo the oouplo and apparatus.

noel said sootions so as to form, in otl'ool ,ono oontmuons oonplo.

My invention will host. ho understood whon dosorihod in oonnootion with tho nooompany- 1 mgr, drawings, in

Tho ordinary form of thorino-olootrio oo\\ plos oomprisos two elements, a positivo and a nogatiro oloinont, nnitod at ono oinh'ioi'ming tho so-onllod hot, or notivo ond of tho oouplo the terminals of ('onnooted. ln oaso of insnoh as the burning out o to ropiaoo the onwhioh is a ooniparativoly oxpensivo' operation. l urthormmo, tho ordinary oouplo can be sot up only tompui'nlil) and thou is usually so plaood that tho oold onds aro suhjootod to diroot radiationi'rom tho furnace and tho liko and tho oouplois frequently in thoway oi tho nttoodunt'. It is i'ho ohjoot of tho prosont iuvontion to oln'iato this dilliouliy and nmlao tho ootor a porniani-nt installation capable of l)oin; looatod so as not. to iniorloro with 0th!!! operation as woll as to idlow of tho qoiok roplaoement of the aotivo part should this ho burned out. or moot with an accident without disturbing the rest of In carrying out; my invention 1 provide a thermo-electrio couple 1, composed of two soparablo sections, a primary or active section '3 and a secondary or othor wu'os are tho hot onds, it is nooossary taro couple by a now 011;,

Into this socket its an ordinary plug carrying the leads (1 and 7, whioh aro oonnooiod in a suitable indioatingor recording dovioo 8. B making thorouplo l separahio tho sooondary sootion 3 may be pornnmootly nttnohod to tho furnaoo-wall Q, as by tho hraokois to, so that the primary sootion may ho insortod and eonnootod when roquirod or it' injured or burned ooh may he qoiokly ro )laood by a new one. The broken ends l of t. W primary and sooorularyseotions mo for this purposo umnootod moans snoh as an opon slot-joint ti and Mogod nut, 12, as shown. Tho onds of tho oonpios are i'nsod or soldorod to tho torminal piooos, whioh are all niado ol' tho sumo inotnl to noutralizo any sooooihu'y thor!no-olootrio oiloots and are prol'ornhl r oi ioppor to insnro u, non-oorrosivo and good oontnot-snrlaoo. This form of oonnootioii is vory simple and oli'ootvivo and also providos a guard against the inoorroor oonnootion of tho olonionts of the two sootions, it being manil'ostly impossible to ounnoot inoorrootly altxor tho terminal piooos l havo onoo hoon proporly 'lusod or soldered to llho oloinonts of tho couple. l do not. wisi V to he understood as implying that to oniploy suoh torminnl piooos oonnootion. as any form of howovor, 1111s nooossory or suoh form oi oouplo sopnrnthlo in pornmnont installation of a part of the apparuins. The feature of being able to remove the ac- 1 Live part. of the couple at will is especially valuable in cases where it is not, desirable to have the couple inserted into the furnace or loin a suitable oomponsating moons, suoh as,

two soi'iionsl :un enabled to oon'nooiion producing a thorough oontnotyf tho terminal piooos mar aoili into the in bath until the latter ger of breaka the couple in c nace, &c.

What I claim as my to secure by Letters Patent, 1s-

1. A thermo-electric couple being separable or capable of division between its hot and cold ends.

2. A sectional or separable thermo-electric couple provided with connecting means be tween t e hot and cold ends. A tl1ermo-electric couple comprising a pr mary section and a secondary section and means adapted to connect said rimary and secondar sections between the 0t and cold ends of t e couple.

4. A theme-electric couple comprising a primary section and a secondary section, and an open slotted joint adapted to connect the is ready because of dane or other possible injury to arging or discharging the fur invention, and desire rim and secondary sections between the ot an cold ends of the couple.

5. The combination with an indicating device or recording instrument, of a sectional or separable thermmelectric couple provided with connecting means between the hot and cold ends.

a 6. The combination with an indicating or recording instrument, of a thermo-electric couple comprising a primary section and a secondary section and means adapted to connect said primary and secondary sections between the hot and cold ends of the couple.
